Working with and Covering Foam Questions
thinned elmers wood glue and brown wrapping paper!
brush the glue/water onto the foam then wrap it with wet paper. the paper shrinks back to size when it dries and makes a super tight and tough skin, much stiffer and lighter than vinyl sign paper and MUCH cheaper than balsa and glass.
i do all my wings this way, even big gassers, and use water based polyurethane paints made for wood.
i used to hate building wings until i found this method.
